A Cladding Pumped Neodymium-doped Fiber Laser Tunable From 932 nm to 953 nm

Research on all-solid-state blue lasers

“…Therefore, high power and high beam quality blue laser around 0.45 µm can be obtained by frequency-doubling technology [14][15][16][17][18][19][20][21][22][23].…”

Compact high-power tunable three-level operation of double cladding Nd-doped fiber laser

“…Nevertheless, the highest output power of tunable laser ever reported is only 32 mW (from 896 to 939.5 nm) using core pumping [6]. Most recently, although by combining two 808-nm pump diodes and bulk diffractive gratings, 2.4-W peak power has been achieved, the laser is bulky, expensive, and far from compact [7]. In this letter, we report a very compact, highly stable, robust, and as high as 810-mW output from a double cladding Nd-doped fiber laser with a tuning range of 15 nm, which we confidently expect to be further extended.…”

Neodymium-doped cladding-pumped aluminosilicate fiber laser tunable in the 0.9-/spl mu/m wavelength range

“…This is in contrast to conventional step-index cores. W-profile cores have been used with germanosilicate neodymium-doped fibers, then allowing a smaller, single-mode, core to be used [14]. However, because of quenching, the maximum neodymium concentration in germanosilicate is limited to 0.1% by weight [9], and in particular with small cores, this leads to undesirably long fibers in which background loss can degrade the performance significantly.…”
